NUREMBURG, Germany — (BUSINESS WIRE) — March 2, 2010 —
As electronic content in cars continues to increase, energy management,
safety and electromagnetic compatibility (EMC) robustness have become
critical requirements for in-vehicle networks. Freescale Semiconductor
today announced its next generation of system basis chips (SBCs) to
address these issues. The SBC devices integrate an energy management
module to power microcontrollers (MCUs), transceiver interfaces to
connect with in-vehicle networks and low-power modes to conserve battery
life.

The advanced MC33904/5S/5D SBCs are built on Freescale SmartMOS
technology and are designed to optimize the performance, power
consumption and cost of electronic control units for a broad range of
automotive applications. The devices are ideal for high-performance body
applications such as body control modules, lighting modules, door/seat
modules, seatbelt pretensioners, fuel/water pumps, glow plugs and
low-end engine management systems. They also are suited for applications
including safety and powertrain.

EMC and electrostatic discharge (ESD) are a serious concern in harsh
automotive environments due to the close proximity of a wide range of
networked electronic systems and devices. These CAN/LIN-certified
devices offer programmable fail-safe features to assist with system
functional safety, while providing a high level of ESD protection and
excellent EMC performance to address stringent automotive requirements.
The SBCs are AEC-Q100 automotive qualified and are highly immune to EMC
and ESD stresses without the need for external components, simplifying
the bill of materials. Innovative wave-shaping technology helps enable
ultra-low electronic emissions.

“Freescale has more than 20 years of experience developing sophisticated
power management solutions for the automotive market,” said Scott Ward,
vice president and general manager of Freescale’s Analog, Mixed-Signal
and Power Division. “Our latest SBC product family is designed to offer
automakers a scalable solution to enhance system reliability and
robustness, and reduce power consumption in automotive networks.”

The pin-compatible family of SBC devices are ideal companion chips to
Freescale 16-bit and entry-level 32-bit automotive MCUs. The devices
contain a combination of low drop out (LDO) voltage regulator(s),
high-side switches and physical layer transceivers (CAN, LIN). The SBC
devices are controlled by an MCU through a serial peripheral interface.
They also possess various power-saving modes such as standby, sleep and
stop and other features including wakeup and watchdog timer. The new
family of SBCs includes:

MC33904 – SBC with high-speed CAN transceiver

MC33905S – SBC with high-speed CAN and 1LIN transceiver

MC33905D – SBC with high-speed CAN and 2 LIN transceivers

Development support, price and availability

The MC33904, MC33905S and MC33905D devices are available now in
10,000-piece quantities for a suggested resale price of $1.54, $1.78 and
$2.08 (USD), respectively.

To help accelerate time-to-market and demonstrate the benefits of the
multiple embedded functions of the SBC devices, Freescale offers a
development kit that comes with a PC graphical user interface software
program. The KIT33905D5EKEVBE evaluation platform contains the necessary
components, except for the KITUSBSPIDGLEVME interface board that is sold
separately, for evaluating the MC33905D.

The KIT33905D5EKEVBE is available for a suggested resale price of $100
(USD).
